Agra Fort is a UNESCO World Heritage site(1983) located 2.5 km northwest of Agra, India. One of the most impressive monuments in Agra after Taj Mahal is the Agra Fort. The fort is also known as Lal Qila, Fort Rouge and Red Fort of Agra which is a veritable treasure trove of the Mughal architectural tradition. The great Mughal lived here and governed from here.

Agra Fort has a history that spans two generations of the Mughal emperors. Started during the reign of the Mughal emperor Akbar (1556-1605), the construction work on the Agra Fort continued till the reign of his grand son Shah Jahan (1627-58). Though started by Akbar in 1565, it was Shah Jahan, who constructed most of the buildings inside the fort. Agra fort was also a site of one of the centres during the Indian rebellion of 1857, which caused the beginning of the end of the British East India Company's rule in India, and led to a century of direct rule of India by Britain.

The Agra Fort has a mighty wall made of red sandstone, which runs for 2 ½ Kilometers around the perimeter of the fort. The main entrance to the Agra Fort is through a grand gateway called the Delhi Gate, which is decorated with inlay work in white marble. Shah Jahan was imprisoned in the Agra Fort by his son Aurangzeb, when he took over the Mughal throne. Shah Jahan spent the last years of his life in the Agra Fort, where he is said to passed his days looking from the balcony of the Mussaman Burj, a tower in the Agra Fort,

towards the Taj Mahal, where his beloved consort Mumtaz Mahal was buried. You can also view the Taj Mahal from the Agra Fort, on your tours to Agra India
